FB2:
The output terminal of ch.2 error amplifier.
Its source current is
25
μ
A typ. and sink
current is 8 mA typ.
Correct the frequency characteristics of the
gain and the phase by connecting a resistor
and a capacitor between the terminal and
IN
2 terminal.

DTC2:
1) Terminal for connecting a resistor and a
capacitor for setting the dead-time and the
soft start period of ch.2 PWM output.
Input current I
DTC
is determined by the tim-
ing resistor RT so that dispersion, and fluc-
tuation with temperature are suppressed. The
input current is

2) The ch.2 output can be turned off by reduc-
ing the terminal voltage to below 0.12 V.

Out2:
The ch.2 open-collector type (Darlington)
output terminal.
The absolute maximum rating of ouput cur-
rent is 150 mA.
Use with an output current under 100 mA
normally.
